Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a synchronous casting template for backrests on both sides of a curbstone. Background Art

[0002] Curbstones are marker stones placed between the road surface and other structures. Curbstones are typically installed between the median and the road surface, and between the sidewalk and the road surface, on urban roads. To ensure the stability of the curbstone structure, a backrest structure is required on one or both sides. The synchronous casting formwork for the backrest on both sides of the curbstone is a critical tool for simultaneously pouring concrete on both sides of the curbstone, ensuring its quality and accuracy.

[0003] After searching, the patent number "CN219174945U" mentioned in the text that "the utility model relates to the field of road construction technology, specifically a curbstone backrest casting formwork, comprising: a cross brace and an adjustment rod are provided on one side of the fixed rod, a connecting rod is provided on the other side of the fixed rod, a positioning rod is provided at the end of the connecting rod, and a slot is provided on the surface of the positioning rod; a formwork plate is provided on one side of the positioning rod, and an insert plate and a reinforcing rib are provided on the surface of the formwork plate; a movable rod is provided at the end of the cross brace, and a lifting groove and a side groove are provided on the surface of the movable rod, a sleeve block is provided inside the lifting groove, and a pressure block is provided at the end of the movable rod; the beneficial effect is: by clamping the fixed rod and the pressure block on both sides of the curbstone, and then fixing the formwork plate to the back of the curbstone by the positioning rod, the curbstone backrest is cast between the formwork plate and the curbstone, so that the quality of the appearance of the curbstone backrest can be guaranteed, and the stability of the curbstone backrest can be guaranteed at the same time." This device can ensure the quality of the appearance of the curbstone backrest and the stability of the curbstone backrest.

[0004] While the construction method and supporting formwork that uses a backrest on one side of the curb are more common, supporting formwork that uses backrests on both sides of the curb is less common. The conventional construction method involves placing curbs on the pavement base, erecting formwork on both sides of the curb, and using steel bars or gantry frames as external supports for the formwork. Bricks are used as internal supports between the formwork and the curb. This method is time-consuming and labor-intensive, and is prone to back-and-forth sliding, which can cause formwork to slip during pouring.

[0005] Therefore, we provide a synchronous casting template for the backrests on both sides of the curb to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a synchronous casting template for the backrests on both sides of the curb stone, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a template for synchronously casting backrests on both sides of a curbstone, comprising a template and a support mechanism, wherein the support mechanism is installed on one side of the template, a backrest is provided on the other side of the template, and a curbstone is provided on the other side of the backrest;

[0008] The supporting mechanism includes a template back rib, a clamping assembly, a push rod assembly and a strut assembly.

[0013] Preferably, the connecting rod passes through the screw hole of the vertical back rib, and the connecting rod is screwed together with the vertical back rib thread.

[0014] Preferably, four nuts are connected to the through-length screw, one nut each at the front and rear of the vertical back ribs on both sides.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the setting of the template back ribs and clamping components, when in use, the cooperation of the horizontal back ribs and the vertical back ribs provides stable support and rigid structure, so that the template can maintain its flat shape and verticality. The user adjusts the distance from the pressure plate to the vertical back ribs by turning the connecting rod with the handle, using the vertical back ribs as a lever and the support rod assembly as a fulcrum, and then applies thrust to the pressure plate through the connecting rod, so that the two pressure plates are clamped and fixed on the curb, completing the installation and fixation of the template and the curb.

[0017] 2. Through the arrangement of the push rod assembly and the support rod assembly, when in use, the casing is rotated forward so that the short-section screws on both sides are screwed into the casing, thereby tightening the vertical back ribs on both sides; when the casing is rotated backward, the short-section screws on both sides are screwed out of the casing, thereby applying outward thrust to the vertical back ribs on both sides to open the vertical back ribs on both sides; through the cooperation of the through-length screw and the nut, when the nuts in front and behind the vertical back ribs clamp the vertical back ribs, the distance between the vertical back ribs on both sides is fixed; when the push rod assembly pushes the vertical back ribs outward, the support rod assembly can provide reverse supporting force; during the backrest pouring process, the vertical back ribs are assisted in fixing by the nuts on the inside of the vertical back ribs to prevent the bottom of the formwork from exploding.

[0018] To sum up, when using this device, one person can complete the support and removal of the formwork for the synchronous casting of the backrests on both sides of the curb. When supporting and removing the formwork, only a wrench is needed. The curb is used as the supporting structure of the formwork. When casting the backrests on both sides, the curb is used as the fulcrum to react to each other, avoiding the problems of sliding back and forth and running of the formwork. When removing the formwork, there is no need to hit the formwork with brute force, which causes less damage to the formwork and the formed backrest. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 As shown, the utility model provides an embodiment: a template for synchronously casting backrests on both sides of a curbstone, comprising a template 1 and a support mechanism 2, wherein the support mechanism 2 is installed on one side of the template 1, a backrest 3 is provided on the other side of the template 1, and a curbstone 4 is provided on the other side of the backrest 3;

[0026] The supporting mechanism 2 includes a template back rib 21, a clamping assembly 22, a push rod assembly 23 and a strut assembly 24. The template back rib 21 is installed on one side of the template 1, and the clamping assembly 22 is installed on the other side of the template back rib 21. The push rod assemblies 23 are installed on both sides of the top of the template back rib 21, and the strut assembly 24 is installed on the bottom end of the push rod assembly 23.

[0027] Furthermore, the template back rib 21 includes a horizontal back rib 211, a vertical back rib 212, and a vertical long hole 213. The horizontal back rib 211 is fixedly connected to one side of the template 1, and the vertical back rib 212 is fixedly connected to both sides of the horizontal back rib 211. The surface of the vertical back rib 212 is provided with a vertical long hole 213. Through the setting of the template back rib 21, a stable support and rigid structure are provided, so that the template 1 can maintain a planar shape and verticality.

[0028] Furthermore, the clamping assembly 22 includes a handle 221, a connecting rod 222 and a pressure plate 223. A handle 221 is provided on one side of the vertical back rib 212, and a connecting rod 222 is fixedly connected to one side of the handle 221. A pressure plate 223 is installed on the other end of the connecting rod 222. Through the setting of the clamping assembly 22, the vertical back rib 212 is used as a lever, and the support rod assembly 24 is used as a fulcrum. A thrust is applied to the pressure plate 223 through the connecting rod 222, so that the two pressure plates 223 are clamped and fixed on the curb 4, thereby completing the installation and fixation of the template 1 and the curb 4.

[0029] Furthermore, the top rod assembly 23 includes a short-section screw 231 and a sleeve 232. The top of the vertical back rib 212 is installed with a short-section screw 231. The threads on the short-section screws 231 on both sides rotate in opposite directions. The other end of the short-section screw 231 is threadedly connected to the sleeve 232. The sleeve 232 includes two sections of threads with opposite rotation directions. Through the setting of the top rod assembly 23, when the sleeve 232 rotates forward, the short-section screws 231 on both sides are screwed into the sleeve 232 to tighten the vertical back ribs 212 on both sides. When the sleeve 232 rotates reversely, the short-section screws 231 on both sides are unscrewed from the sleeve 232, which can apply outward thrust to the vertical back ribs 212 on both sides to open the vertical back ribs 212 on both sides.

[0030] Furthermore, the strut assembly 24 includes a full-length screw 241 and a nut 242. The full-length screw 241 is installed at the bottom end of the short-section screw 231. One end of the full-length screw 241 passes through the vertical long hole 213. The surface of the full-length screw 241 is sleeved with a nut 242. Through the setting of the strut assembly 24, an inward pulling force can be provided to the vertical back ribs 212 on both sides. At the same time, when the top rod assembly 23 supports the vertical back ribs 212 outward, a reverse supporting force can be provided.

[0031] Furthermore, the connecting rod 222 passes through the screw hole of the vertical back rib 212, and the connecting rod 222 is screwed together with the vertical back rib 212, so that the user can adjust the distance from the pressure plate 221 to the vertical back rib 212 by rotating the connecting rod 222 through the handle 223.

[0032] Furthermore, four nuts 242 are connected to the full-length screw rod 241, one nut 242 at the front and rear of the vertical back ribs 212 on both sides. During the casting process of the backrest 3, the nuts 242 on the inner side of the vertical back ribs 212 are used to assist in fixing the vertical back ribs 212 to prevent the bottom of the formwork 1 from exploding.

[0033] Working principle: first, cast the template of the backrest on both sides of the curb stone synchronously to the working position. When in use, the first step is to loosen the nuts 242 before and after the vertical back rib 212, and the nuts 242 are away from the vertical back rib 212, so that the vertical back rib 212 can rotate around the hinge axis of the short-section screw 231. At this time, the templates 1 on both sides are opened. The second step is to rotate the connecting rod 222 through the handle 221 to adjust the distance from the pressure plate 223 to the template 1 to be consistent with the width of the backrest 3. Rotate the sleeve 232 to stretch the top rod assembly 23 until the two templates 1 are parallel. At this time, the pressure plates 223 on both sides are against the side of the curb stone 4. The third step is to adjust the nuts 242 on the outside of the vertical back rib 212 to be close to the vertical back rib 212, continue to rotate the sleeve 232, the push rod assembly 23 supports the vertical back rib 212, so that the pressure plate 223 is clamped on the curb 4, and then the nut 242 on the inner side of the vertical back rib 212 is rotated until it is close to the vertical back rib 212. In the fourth step, when the backrest 3 is solidified and the mold is removed, the nuts 242 on both sides of the vertical back rib 212 are moved away from the vertical back rib 212, and the pressure plate 223 is moved outward so that the pressure plate 223 does not contact the curb 4, and then the sleeve 232 is continued to be rotated to make the push rod assembly 23 continue to extend, and the extended push rod assembly 23 continuously pushes the vertical back rib 212, and then the template 1 is demoulded, thus completing a process of using the template for synchronous casting of the backrests on both sides of the curb.
